2. Description of the Related Art FIG.
It is a figure which shows the compensator rope expansion | contraction amount confirmation apparatus of the conventional elevator described in the 0 publication, 1 is a car of an elevator, 2 and 3 are the hoisting machine sheave for hoisting the car 1, and the hoisting machine trolley car. is there. A counter 5 is connected to the other end of the main rope 4, one end of which is connected to the car 1. on the other hand,
One end of the compensating rope 6 is connected to the bottom of the car 1,
The other end is connected to the counter 5 to suspend and support the compensator 7. A counter proximity switch 8 is provided in proximity to the counter 5 to detect its position, and a compen proximity switch 9 is provided in proximity to the compen 7 to detect its position. The output signals of the counter proximity switch 8 and the compensating proximity switch 9 are respectively the counter position signal transmission cable 10
And the compensator position signal transmission cable 11 are connected to the compensator rope extension amount calculation personal computer 12.
The personal computer 12 for calculating the amount of expansion of the compensating rope includes the position signal of the counter 5 output from the counter proximity switch 8 and the compensator 7 output from the compensating proximity switch 9.
This is a personal computer that calculates the amount of expansion of the compensating rope 6 by the position signal of. Further, 13 is the lowest floor hall, 14 is the highest floor hall, 15 is a hoistway wall, 16 is a pit, 17 is a pit floor, and the counter proximity switch 8 is the hoistway wall 15

【Example】

Example 1. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing the overall configuration of the first embodiment, and the configuration from the car 1 to the car shock absorber 19 is the same as that of the conventional example. A reference numeral 20 is a machine room control panel 20 installed in the elevator machine room, and a detection computer 21 for inspecting equipment in the pit is provided therein. Reference numeral 22 is a cable for inspecting and inputting each device in the pit, which is a counter clearance measuring sensor 23 as a clearance detecting sensor, a compen clearance measuring sensor 24, a speed governor-tension vehicle clearance measuring sensor 25,
Also, a water level detection switch 26 for measuring the presence or absence of submergence is connected. Further, 27 is a cable for outputting inspection signal of each device in the pit, to which a monitor 28 for inspecting each device in the hall operating panel and pit is connected. 29, 3
0 and 31 are the compensator 7 and the governor-tension car 3, respectively
2, a sensor reflector attached to the counter 5, 33 a speed governor rope, and 34 a speed governor. Machine room control panel 20
An inspection display remote reporting device 35 is attached to the remote display monitor 36 and is connected to a remote display monitor 36 by a cable.

FIG. 2 is a front view of the equipment inspection and display monitor 28 in the hall operating panel and pit. The car call push button 37, the counter clearance, the speed governor-tension vehicle clearance, the compensator clearance, and the presence / absence of flooding were measured. An inspection display monitor panel 38 for displaying the results is provided. Each inspection display monitor panel 38 is provided with an inspection normality display LED 39, an inspection caution display LED 40, and an inspection abnormality display LED 41, respectively.

FIG. 3 shows a logic image of the detection computer 21 for inspecting equipment in the pit incorporated in the machine room control panel 20. The input signal is sent to the CPU through the I / O and interface, and the logic is generated by the CPU. The result of the dynamic analysis is output as an output signal to each equipment inspection display monitor 28 in the hall operating panel and pit via an interface. It is also possible to issue a remote report using a telephone line.

Next, the operation of the above device will be described.
Since any of the above detection / display operations is the same, the case of measuring, detecting, and displaying the compen clearance will be described below.

The compensating clearance measuring sensor 24 is
The physical quantity obtained from the sensor reflection plate 29 attached to the lower end of the compensator 7 is constantly measured and detected, and the measured value at each time is used as a signal to inspect equipment in the pit via the input signal transmission cable 22 to detect the equipment in the pit. 21
Send to. This measured value changes due to the elongation of the main rope.

Detection computer 21 for inspecting equipment in the pit
Is a signal converted by the interface based on the transmitted signal and compared with the judgment size stored in the logic of the CPU. If the converted signal is within the allowable value, it is a normal signal, and if it is the limit value of the allowable value. If the signal is a caution signal or out of the allowable range, an abnormal signal is output via the interface.

The stored judgment dimensions are allowable values for the counter clearance, the compensating clearance, the submergence, and the speed governor-tension vehicle clearance. However, in the case of counter clearance, it is a condition that the car 1 is located at the level of the top floor hall 14. The signal output from the CPU is transmitted to the equipment inspection output signal transmission cable 27 in the pit to the equipment inspection display monitor 28 in the hall operating panel and in the pit to display the inspection state of each equipment. In addition, CP
The signal output from U is sent to the remote display monitor 36 via the telephone line by the inspection display remote reporting device 35, so that the inspection can be performed from a remote place such as a manager's room.

When the inspection display monitor 28 for each device in the hall operation panel and pit is normal, only the inspection normal display LED 39 is lit, in the case of caution, only the inspection caution display LED 40 is lit, and in the case of abnormality, the inspection abnormality is detected. Display LED 41
Only lights up. Since any one of the inspection normality display LED 39, the inspection caution display LED 40, and the inspection abnormality display LED 41 is constantly lit, at the time of inspection, it is easy to inspect the clearance of each device and the presence or absence of flooding without looking into the pit from the landing. It is possible to

According to the present embodiment, it is not necessary to inspect each device by detecting the amount of extension of the rope as in the conventional example, and the state of the clearance defined by the standard can always be detected in time series. Since normality, caution, and abnormality can be determined, it is possible to predict abnormality in advance and take appropriate measures to always provide constant quality.

Also, with the advantage that the state of each device can be judged from the landing without having to go to the machine room, the inspection display monitor is located at the lowest floor landing, so the comparison verification with the actual product is the same position. Since it also has the advantage that it can be done simultaneously, defects such as computer bugs can be verified at the same time, and accuracy can be increased.

Example 2. Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is an explanatory diagram of the main part of the second embodiment, in which a falling object detection sensor 42 for detecting a falling object is installed on the pit floor 17 just below the threshold of the lowest floor hall 13 and the falling object 43 is When it hits the falling object detection sensor 42, a signal is transmitted to the pit device inspection computer 21 through the pit device input signal transmission cable 22 for processing, and each pit device is processed as in the embodiment of FIG. The inspection output signal transmission cable is sent to the display monitors in the halls and in the manager's room, and it is possible to detect the presence or absence of a fallen object, which enables more reliable inspection of the equipment in the pit.
